Synthesis and Conformational Flexibility of 4,9‐Dihydroindolo[3,2‐ d ][1,2,4]triazolo[4,3‐ a ]benazepines Herrn Prof. Dr. P. Nickel zum 60. Geburtstag gewidmet Indolotriazolobenzazepines 6 are prepared by cyclisation of thiolactam 4 with acylhydrazides 5 . The influence of the 1‐ substituent on the barrier of ring inversion of the new ring system 6 is studied by dynamic 1 H‐NMR spectroscopy.
